WINDOW-LOCK:

Specification of Letters Patent. Patented Feb, 24:, 1920.

. Application filed February 24,1919. SerialNo. 278,840.

To all whom it may concern:

Be it known that 1, JAMES B. PHILLIPS, J r., a citizen of the United States, residing at Longcreek, in the county of Oconee and State of South Carolina, have invented certain new and useful Improvements in Window-Locks, of which the following is a specification.

This invention relates to looks and more particularly to window looks.

The primary object of this invention resides in the provision of a window lock having means whereby the window may be retained in either a closed or partially opened position with the possibility of further manipulation from the exterior of the dwelling prevented.

Another object of this invention resides in the provision of a window lock having means whereby the manipulation of the looking elements is accomplished during the tendency to raise the window.

With these and other objects in view this invention resides in certain novel features of construction, arrangement of elements and combination of parts which will be hereinafter more fully described in the specification and illustrated in the accompanying drawing wherein:

Figure 1 is a View of a window frame and sash with parts broken away and in section.

Fig. 2 is an enlarged sectional view on line 2-2 of Fig. 1.

Fig. 3 is a detail perspective view of the locking bolt.

In the present embodiment of this invention the numeral 5 designates 'a window frame of any approved or well known construction which slidably retains a window sash 6 also of a well known-design.

Slidably held in an end entering horizon-' tal bolt bore of the bottom stile of the window sash 6 is a locking bolt 8 which has a laterally offset inwardly directed head 10its outer end provided with the leveled end as at 12 in order that it will co-act with a rack 14 that is rigidly secured to the window frame in any approved manner that insures its cooperation with said bolt 8 in preventing the window from being opened from the exterior thereof. The inner end of this bolt 8 is reduced in thickness as at 16 for the accommodation of a hook ended actuating lever 18 that is pivoted thereto as at 20 in an upwardly directed opening extending from the bore, as shown, fulcrumed as at 22 in order that said bolt may be manipulated against, the tension of a spring 24 which urges the bolt outward and tilts the hook ended levers downwardly as the handle 26 of said lever is drawn toward the window lifts 28 bythe tips of the fingers of a person during the upward movement of the sash.

' The aforesaid rack 14 while being herein disclosed as having teeth 30 that prevent the window from moving in but one direction while the bolt is engaged therewith, may be of such construction that the bolt when engaged therewith will prevent its movement in either direction until it is entirely re leased therefrom.

The lever 18 heretofore referred to is disclosed as being directly under the window lift 28, but since its operation is equally as successful with the handle 26 offset it can be employed with window lifts that are mortised in the inner face of the sash.

With this invention as herein set forth it is apparent that a successfully cooperative combination of elements are provided at a nominal expenditure and the right is reserved to resort to any minor changes that come within the scope of the present claim.

Thus having described this invention what I claim is:

The combination of a window frame and the sliding sash therefor, the lower rail of the sash having a longitudinally disposed recess therein communicating throughout its length with the inner face of the rail, a lock bolt arranged for longitudinal movement in said recess and being of less length than ,the said recess, the said bolt being of less width than the depth of said recess, a laterally directed offset head on the outer end of said bolt projecting beyond the inner face of said sash, a vertically disposed rack bar on said window frame in close proximity to the inner face of the stile of the sash preventing inward movement of the latter and in the path of said head, a plate covering said recess and flush with said sash rail and having a notch infits outer end of equal width with the thickness of said head and receiving the latter, the said sash rail having a vertical bore communicating with the inner end of said recess, a lever pivoted intermediate its ends in said bore and connected at its lower end with said bolt, a spring seated in the inner end of said recess and pressing against the lower end of said lever to normallyforce said head in engagement with the said rack bar, a handle on the upper end of said lever above the plane of the said sash rail, and a lift on said rail spanning said handle.
